We first have to wait to see if the US Open decide to go ahead. I'd say a final decision on that will be made within the next week.Top 50 players not entered in WTA 'Cincy' (via TennisForum):
Barty, Halep, Svitolina, Andreescu, Osaka, Martic, Kerber, Wang, Pavlyuchenkova, Zheng, Stephens, Goerges, Ostapenko, Hercog.
That's 7 slam champions missing (one expects some of them still play USO though)..
That is a lot of talent not doing a lead up event. 1 has confirmed no US swing. Let's see who else
If it is going to go ahead, it will be a hot mess. I'd say many top players outside of America will be missing. Could make for a very interesting tournament. If Serena wins Number 24 with a very weakened field, how do we feel about that?
In 30 years time her slam tally would still say 24 and there would be basically no discussion on her 24th slam being illegitimate.
